After reviewing community feedback, Ethan Heilman and I have enlisted the help of a third co-author, Isabel Foxen Duke <https://x.com/isabelfoxenduke>, in an editorial role to lead and execute a clean sheet rewrite of BIP 360.
Because previous revisions introduced meaningful technical changes, we determined that a full rewrite, rather than incremental edits, was warranted to improve clarity, internal coherence, and to better articulate our intentions for managing potential quantum-related risks. Consistent with its previous version, this proposal does not introduce post-quantum signature schemes. Instead, BIP 360 proposes the addition of a new output type with the key path spend removed, which is thus protected from hypothetical breaks of Elliptic Curve Cryptography (ECC). We have renamed this proposed output type "Pay-to-Tapscript-Hash (P2TSH)" for clarity, and believe its adoption is an important first step in protecting Bitcoin from potential threats to ECC, via quantum computers or any other cryptanalytic advancements. Additionally, the proposal now includes test vectors in Python and Rust. With gratitude, we hope you’ll review these changes in the BIP Repo <https://github.com/bitcoin/bips/pull/1670> or at BIP360.org <http://bip360.org>. We look forward to ongoing community feedback, and new ideas in our efforts to Make Bitcoin Quantum Resistant.
